I was siting in my living room writing when my eye was dawn to the blue sky outside my window. I, at first, saw only blue sky with puffy white clouds here and there but then seeing motion I looked to the northwest, very high in the sky, and saw what at first looked like a jet travelling very fast almost straight down. It had that bright dot.small orb, of white light that most jets appear like, almost teardrop in shape with the pointing end of the drop behind the rounded part. It left a trail much like a jet would but it dissapated quite slowly.Something about the trail it left seemed off, can't really explain why, so I continued to watch the moving object and saw it seem to disappear for maybe 7 seconds only to reappear again but a little off from it's original path, a little more west, but still straight down and it disappeared into the cloud below it.It never came out.I don't know what the heck that was, possibly stealth of some kind or maybe something else. I have never seen anything like this just disappear and not come out of a cloud.I watched for several minutes afterward to see if the small dot of light would come out somewhere around that large cloud but it never did (well that I know of anyways).Just left me with a feeling that this wasn't just a jet.
